All fragrance terms are actually just designators for different dilutions of perfume oil. Fragrances are, in a nutshell, blends of different plant oils and synthetic oils, but to make them spritzable and less overwhelmingly potent, perfumers water them down with (usually) ethyl alcohol. So when someone talks about and Eau de Parfum or an Eau de Toilette, what they’re really talking about is just an oil to alcohol ratio. Here’s a fast breakdown of what those ratios mean, from strongest to most dilute:
Eau de Toilette
The Eau de Toilette (EDT) it is commonly known, is the most popular strength in the fragrance family. With a concentration of aromatic oils up to 15% but usually around 10, the Eau de Toilette is the happy medium between an airy Eau de Cologne and a punch of Parfum. EDT is designed to only last 3-4 hours and is cheaper, but in no way is it any less than the real deal, most Men Perfumes are sold in EDT or a Eau de Cologne.

Eau de Parfum
Eau de Parfum (EDP) is another very common fragrance type, although a little richer in scent than an Eau de Toilette.
Eau de Parfums can be expected to last on the body longer, and have up to 20% concentration of aromatic compounds.
Some people reserve their Eau de Parfum for the evening and only wear an Eau de Toilette during the day, but there are no real rules when it comes to fragrance!
